'IMPRovi-:MENT 1N REFRIGERAroRs.

The Schedule referred ta'in these Letters Patent and making part: of thesame.

To all persons to fw/tom these presents may camel' -Be it known that I,ANDREW JACKSON CHASE, of Boston, of the county of Suffolk and State otMassay "chnsetts, have inventedV an Improved Refrigerator; p and dohereby declare the same-to be fully described inthe followingspecification and represented in the accompanying drawing, ofg'yvhichmvFigure l is-a transverse section, andA Figure 2 a long'udinal section ofit.

In such drawing--- y j A' denotes a box, having an opening,` a, at itstop,

and another, b,'in vits side, such openings being furnished' with coversor doors, c d, for closing them.

In carryingrou't my invention I arrange within the i said box, directlyagainst one side oi' it, and at or near the upper part ot' such. sido',an inclined apron, D, which l' usually make of sheet inetal, theinclina. tion of the apron causing it to stand at anacutefangle with``the next Vadjaceutside of'. the box, such being'- as shown in tig. 1.VThe apron extends entirely across .the interiorof the box, from one tothe other of the ends of it. .Y

` At itslower end the' said apron terminates against another shortinclined apron, F, arranged at or about Aat a right angle with Atheiirst one.

- `Underneath the junction ot' the two aprons is 'a trough, H, whichextends across the box from end'to l y end, and has a duct leadingthrough one end.

At the junctiony ot' the' two aprons, or directly over the trough,vtheresl'iouldlbe made, in eitherapron or in both, one o r more holes forvdischarge of water into the' trough, which trl'mgh should be open attop, and be` arranged with referencetolthe lower sides of the twoaprons, in manner as represented, in order 'that any vapprfthatmaybefcondensed on suchsides of the aprons shallyafter running ldown`such sides, drop or fall into thetrough. 4 Y The block or blocksof icefor cooling the air'within Vthe box are to beplaced onjtheftwo aprnsinmanner as shown at I.

Tlie modes" in which the air within the box will be caused to circulateby theice are exhibited, intig. 1,'

"In making my present refrigerator I have avoided the 'employment ofvanyair-passages between vthe upper edge 'of the apronD and -the nextadjacent side of the case, the apron being fixed close' against suchside, thereby Yexpressly avoiding any air-passage and al1 circulationofthe air.Y between the upper edgeiof the apron andsuch side. In thisrespect myrpresent refrigerator differs from that for which LettersPatent N011o,112, l(need December 13, 1870, have been granted to me.

In my present refrigerator I get much more room in the case for thepacking or hanging or stowage of articles to be cooled or kept in a coolstate.'

I am also enabled to manufacture the refrigerator cheaper and to betteradvantage, relatively to the said patented re'igerator.

By dispensing With the aii-Lpassag'e between .the side of the case andtheupper edge of the inclined apron F the air is caused to'have acirculation in two currents, one under and the other over the ice, the

current' going over the ice and against the top of the case: beingArefiected or turned 4back over the icc 'in a manner to be bettercooledrthan it would if suffered to iowu'p through an opening at theupper edge of the apron, and thence directly across the ice. The

Yauxiliary current isv caused by the cooling powers of the lower side ofthe longer' apron. y

The inclined positions of the two aprons, and theV disposition of thetrough with respect to them, not

l only enable the vaprons to support the ice, but to conduct into thetrough the waste of the ice, as well as the vapor thatmay becondensed-on such aprons.

The refrigerator is found to operate with remarkable efciency, and, ashcreinhefore mentioned, not only to be better calculated for receivingand holding articles to be cooled or preserved, but to. b'e cheaper 'inconstruction'in respect t'o that. described in my said patent.

It will be observed that, in this refrigerator, I combine the means ofproducing the reden current over the ice,fvvith, the peculiararrangement of the two aprons and their trough, whereby not only is theice disposed to great advantage for cooling from all its surface, butits waste/as well as the condensed' vapors are carried oli" withoutfalling upon any article'or articles when beneath?l the parts forsupporting the ice I therefore claim as my. invention- The improved`reirigerator, composed of the case, and the two aprons andA trougharranged within such case, substantially as described and represented,the arrangement involving they longer-apron applied to the next adjacentsideof the case, sot-hat there may. be no `passage between such side andthe upper edge' v ot'fthe apron for the air of the'box to circulatethrough,

all being as set'forth. l
